That first patent by Bell was the ""master patent"" of the telephone, from which other patents for electric telephone devices and features flowed. In 1876, shortly after the telephone was invented, Hungarian engineer Tivadar Puskás invented the telephone switch, which allowed for the formation of telephone exchanges, and eventually networks. Early telephones were technically diverse. Some used a water microphone, some had a metal diaphragm that induced current in an electromagnet wound around a permanent magnet, and some were dynamic"
"Telephone A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. In 1876, Scottish emigrant Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice. This instrument was further developed by many others."

On 26 July 1874 in their living room the younger Bell realized the technical principles of telephony, inventing the telecommunications device he is now closely identified with. Returning again to the Homestead the next summer in 1875 Bell wrote his first draft specifications of the telephone patent—commonly considered to be the most valuable patent in history—that September. He later built his first fully functional unit at Boston on 10 March 1876."
